The question was posed to me in an interview for job.

Asked question is from Using the Database Access Program ENTREZ in division Collecting & Storing Sequences in Laboratory of Bioinformatics

Answer 1

Correct choice is (a) AND

Easiest explanation: On the ENTREZ form, make a selection in the data entry window after the term “Search,” then enter search terms in the longer data entry window after “for.” The database will be searched for sequence database entries that contain all of these terms or related ones.
